Far out indeed. I think I've seen that picture, or one very like it, before. That bizarre bubble. It's beautiful, in a frightening way.

I cannot figure out how they made a camera so fast. Think of how fast the film had to move, if a movie
camera. Maybe it was just a bunch of simple one-shot single cameras, with a fancy nanosec trigger,
but what mechanical thing could move that fast? Baffling. :eek:

The tech and guts in the bomb are pretty interesting. They use "blasting caps" that are extremely fast,
the ultimate in electrical pulse generation. It is a vacuum tube, no solid state device can handle the HV.

Unlike most other gas switch tubes, the krytron uses arc discharge.

An electric arc is an electrical breakdown of a gas which produces an ongoing plasma discharge, resulting from a current flowing through normally nonconductive media such as air. A synonym is arc discharge. The phenomenon was first described by Vasily V. Petrov, a Russian scientist who discovered...

Not exactly the rite depiction, that cannot be described.. :twisted:

Your instincts are correct. A "bunch" of cameras with fancy, non-mechanical shutters.

Thanks Mee_n_Mac

I was wondering about the spikes in those shots and your links lead me this one.

Good new Mac! I have heard of Kerr cells used to optically switch laser beams. Polarizers, hmmm. Clever dudes

back then.
